I was wondering if you can easily sleeve a non modular psu, i was looking at the nzxt hale90's because they would look nice in a nzxt switch 810 because of there color, but i want to sleeve the cables. i was wondering if i could just cut the sleeving down to the end without opening the unit and custom sleeve to there, or is there a special trick i don't know like being able to completely remove the existing sleeving.
